Gah... Laptop issues are not fun. My college requires that students use the school's antivirus software, and of course they use the cheapest, least-effective software out there that no one else ever uses. I've gotten a virus around once a month from just regular web surfing (facebook, pinterest, TFK, the school's website, etc.) and am seriously miffed at the school's IT department for never being able to debug my computer.
Also an anti-rant - We're coming up on a week-long Winter Break, so everyone going home has to check out of their dorm, which means unplugging everything, shutting/latching the windows, and other basic stuff. They expect everyone to take their fish home or leave them without heaters (well, actually, most students or hall staff don't think pet fish need heaters, but that's another story entirely). I went to talk to my hall's RHD and he's allowing me to leave my tanks plugged in over break since it'd be a pain to move all 30ish gallons worth of tanks home and back for a week. So I'm only taking my 2.5 gallon shrimp tank and one of the 5 gallons home - much easier.
